ABSTRACT:
The apparatus has a vaporization vessel and a combustion chamber including a burner. Contaminated water is supplied to the vessel, and vaporized. Simultaneously, any oil-based contaminants in the water are combusted or consumed, with excess air being supplied for this purpose. The water vapour and combustion products exit the chamber and may be condensed to recover the water. The recovered water contains a sufficiently low concentration of oil-based contaminants that it may be discharged.
